Traditional vaccines work by introducing a killed or weakened version of a disease into the body, where the immune system spots it and cranks out antibodies against it. Then, if a wild strain of the pathogen comes along later - one that has the power to sicken or kill - the body is ready for it. The new approach is different. Developed by Rhoel Dinglasan, an entomologist and biologist at Johns Hopkins University Hospital, it would instead work within the mosquito gut. (See the top 10 medical breakthroughs...
...Parents of these unimmunized kids know that as long as nearly all the other children get their shots, there should not be enough pathogen around to sicken anyone. But that's a fragile shield. Infectious-disease bugs continue to travel the globe, always ready to launch the next big public-health threat. Pockets of intentionally unvaccinated children provide a perfect place for a disease to squat, leading to outbreaks that spread to other unprotected kids, infants and the elderly. Ongoing measles outbreaks in four states are centered in such communities; one originated with an unimmunized boy from San Diego...
...lightened by hope. Elsewhere that is still not the case. If the developed world can work to globalize wealth, then it should be similarly able to globalize the opportunities for health. At last, a curative army is mobilizing to make that happen. Many women are surely still destined to sicken and die before its work is through, but many more will learn to battle a disease that, for now at least, they can't even name...
...available all over the forest. Western gorillas, by contrast, live mostly on fruit, a scarcer resource that draws different groups of gorillas and chimpanzees to the same trees at different times of day. "They defecate and urinate in and around the trees," says Walsh, leaving infected body fluids to sicken the next group. Gorillas also examine the bodies of dead apes they come upon, perhaps because they're smart enough to want to know if whatever claimed that life is a threat to them. This provides another means of direct transmission. Now that the mechanics of the epidemic are known...
